rollers,.and they are placed immediately beneath the upper rollers.

Figs. 1 and 3 show the plate f, and the lower guides, d d, and the lower rollers, e e, and their position with reference to the upper guides and rollers. The plate. can be removed by removing the sliding bar g.

The sliding bar g is seen in each of th'e aforesaid figures. Itis a strip of wood or metal, running the length of beam, and' projecting at each end, as seen in fig. 2. It is made even, excepting at 'i i, where are inclined planes, near the ends of the bar. (See iigs. 2 and 3.) These planes are made to correspond with and fit into the planes h h, cut in the plate f.

Figs. 1 and 2 show the channel and planes in the plate, and the sliding bar. The object of the planes is this: The plate f being free to move, by pushing the bar in either direction, the lower rollers are raised nearer the upper rollers, or are lowered from them, so f as to suit or regulate the thickness of the sheets of wool to be -passed through them.

The sliding bar is kept in place by cross-pieces fastened on at each end of the beam, as seen in iig. l2, or by any suitable fastening.

The device commonly used for evening wool is the tingen which does not evenly spread the wool in even sheets as they are drawn upon the feed-rolls, and are thus" spreadou 'They are apt to twist, also, in vpassing through. There is another device, also, for this purpose, having guildesand a heavylid'on one side, to shut down upon the sheets of`wool as they .pass through to the feed-rollers. v

But my invention possesses advantages over other devices. The rollers are adjustable; the upper rollers maybe taken outfand the drawings from the spools placed within the guides and between the rollers; the rollers are sufficiently heavy to even the wool, and, at the same time, by their turning easily on their axes, the wool can be drawn through without difficulty; and, by adjusting thesliding bar beneath, the sheets of wool may be drawn ine 4or coarse, and at the same time perfectly'even. The device for this purpose is novel, and of great practical utility. I What I claim as my invention, and desire to secure by Letters Patent, is

The combination, with the series of adjustable rolls c c e e and their' guides b b d d, of the plate f and sliding bar g, having inclined planes i i h h, all arranged substantially in the manner and for the purpose set forth.

LYSANDER HOLMES.

To all whom it concern Be it known that I, LvsANDER HOLMES, of Newton, in the county of Middlesex, and State of Massachusetts, have invented an improved device for-evening wool, to produce roping of even size; and I hereby vdeclare that the following is a full .and exact description thereof, 'reference being had to the accompanying drawings, and to the letters of reference thereon, as parts of this specification, of which-'- Figure 1 is a transverse section of the device; Figure 2 is a part section and a part elevation of the same; and

Figure 3 is a partial side view of the rollers and the inclined planes. The letter A represents the beam, to which the device is attached. b b, the upper supports, or guides. c c, the upper rollers. d d, the lower'guides. e e, the lower rollers. f, the plate, supporting the lower rollers and guides g, the sliding bar, for raising the plate f. h h, inclined planes on the plate f. ifi, inclined planes on the bar g. This device is for evening wool, so as to produce roping'of even size, for the purpose of spinning, by taking the wool' in narrow sheets from the. spools. These sheets of wool are drawn between friction rollers, in narrow fiat sheets, (which are, however, of the usual width of doii`errings,) to the feed-rolls, in even width and thickness, so as to produce even roping.

And thatothers may be enabled to manufacture and luse the device, I will proceed to explain it.

Fig. 2, in the accompanying drawings, exhibits .a longitudinal section of the device, showing the rollers, their relative positions, and their supports, and also Vshowing a side elevation of the device."

The letter A,.in said fig. 2, represents the beam, on' which rest and which contains and supports the rollers.- This is made of wood, metahor any suitable material. Upon its upper surface are placed the supports, or guides of the rollers, as b b. These supports, made of metal or any suitable material, are grooved, so as to support the rollers by their axes, as seen in iig. 1, and they are attachedto the beam. The beam has a .channel cut through it to near each end of the same, and is circular at the top, so that the lower rollers come to i the upper surface of the beam, and is of the general appearance seen in ig.,1

Within this channel is set, from the bottom of the beam, the plate f, and upon this plate are secured the guides of the lower rollers, the guides being somewhat similar, and the rollers similar to the upper guides and 1 Witnesses:
